As the industrial market continues to evolve, so does the need for reliable and rugged switching devices. Large battery driven applications, such as forklifts, uninterruptible power supply (UPS) systems, power tools, electric bikes, and other DC motor driven systems are pushing the limits of efficiency and reliability as the need for more power and extended battery life continues to be a staple of newer designs. The need for rugged and efficient MOSFETs is an integral part of these designs. IRs latest offering of power MOSFETs meets the demands of these applications as they offer the best performing devices in the most reliable package offerings on the market.
The new 7-pin D2-Pak, for example, combined with IR’s latest silicon technology offers superior RDS(on) and increased power rating compared to standard D2-Pak devices. A standard three-lead D2-Pak is limited to approximately 100A, depending on lead crosssection and manufacturer’s specification method. IR’s devices have an enhanced 7-pin lead frame that allows a larger wire bond area, reducing die-free package resistance.
The 40V IRF2804S-7PPBF (1.6 mOhm) and the 55V IRF3805S-7PPBF (2.6 mOhm) have a package rating of 160A continuous compared to 75A with the standard D2-Pak. The enhanced current rating allows for a considerable improvement in power density and allows for possible part count reduction in applications where devices are used in parallel. They are an ideal replacement for multiple D2-Pak devices as well as larger through-hole package devices. In addition, repetitive avalanche (EAR) is characterized on the data sheet and guaranteed up to maximum junction temperature (Tj-max).
